SPECIFICATION forming part of Letters Patent N o. 329,238, dated October27,1885-v Be it known that LLOYAL C. TABER, o Danforth, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Traction-Engines, of which the following, taken inconnection with and exact description.

.This invention relates to the tion-engines which have the 'class oftracpropelling-power wheels as well as to the hind wheels, and hasparticular reference to the engine for.which I have obtained LettersPatent No. 294,930, dated March 11, 1884.

' In the manufacture and use of said engine In-the accompanyingdrawings, Figure I is an elevation of my improved tractionengine,. takenat the side which carries the train of gears by which` power istransmitted to the four carrying-wheelsthe engine proper and itsconnection with the driving-shalt being omitted, as such are immaterialto the illustra-v tion and description of the invention. Fig. II

of the traction-engine to which my improvements are applied, said figurebeing partly a sectional view taken'on -line x in Fig. III; and Fig. IIIis a front end view.

Similar letters' of reference indicate corre-- sponding parts. Q

A represents the boiler, which is formed at Said boiler is'supported onthe Iaxles a a at opposite ends,va'nd" engine, and of the greater.portion of the gears falls onto 4the central portion of lthe boiler, therigidity of which has heretofore been depended upon for Yresisting theweight and transmitting it4 to the axles. Experience has proved that theaforesaid weight produces such a strain on the seams of the boiler,especially at the junction of thel forward portion ofthe fire-box withthe boiler, as to weaken or open the seam `thereat. To obviate thisdefect I extend from the bottom of the ire-boxfAto the upperpart of'the'post K, by which the .forward end of the boiler is supported on theserial No. 114,852. (No model.)

axle, a brace, B, which is secured at-its rear end to a knee, f,embracing the bottom cornerofthe forward portion ofthe re-box,andiirmlybolted thereon, said knee being provided with forward-projecting ears "n'n' anda', betweentwo'of which the end of the brace ente-rs, andl 'i issecured thereto by a bolt, o, passing through f said ears and end of thebrace. The lforward end -of the brace is inserted between'lugs ory earsp, formed on the rear of the bearing-post` K, to which lugs or ears thebrace is connected .The traction-wheels W W receive propel-4 ling-powerfrom the driving-shaft C by. means ofa train of gears, F F F F, and aspur-wheel, E, mounted on gudgeons which are secured to the side ofthe'boiuler, aS represented in Fig. .I l

of the drawings. apinion, D', fastened on the driving-shaft, and engagesalso a gear-wheel, O, which in conjunction with other gears,hereinafter-described, transmits motion to the forward axle, a. isprovided on top with a socket or concave step, b, of the form of asection of asphere,. and in this socket is seated the bearir'ig-post K,which is rmly bolted to the under side of the boiler, and has its lowerend of sem'ispherical shape, corresponding tothe socket' Said spur-wheelE meshes in On this axle I fit looselya sleeve, awhich'i b, in which itis stepped. The' boiler is thus mounted on the forward axle by aball-andsocket joint, which allows the said'axle to'oscillatei-n alldirections.

In. order to connethe bearing-post K in the socket b without interferingwith the aforesaid universal movement ofthe. axle, I providethe- 'underside of thejaxle'with'atdownwardapro j ecting studpin, u, to which Iconnect the forward end of the reach r, which 'extends across the underside ofthesl'eeve, and has an eye.

for the reception of said stud-pin. vSaid end of the reach projectsforward 4from the sleeve I s, and isprovidedwith another eye for there-A ception of the, lowervend of a coupling bolt or link, d, which hasits upper end pivoted on the front`of the post K, at a poi-nt in a lineextending horizontally through thc` center of -the sphere formed onsaidpost. Thelower end ofthe linkd passes through the 'end of the reach @andis provided on .the under side roo` c, and on the steering-chains,

thereof with nuts, which hold the reach up against the sleeve s andcomplete the coupling of the ball-and-socket joint between the boilerand axle. The pivotal connection of the link ou the postK allows theaxle tofreely oscillate in a verticalA plane, as indicated by dottedlines in Fig. III of the drawings. The rear end of the reach is insertedbetween the two ears u n of the kneej', and is connected therewith bythe bolt o, passing through it, said knee consisting of a single plaincasting, which has a firm bearing on the shell of the water; jacketsurrounding the fire-box, and serves as a convenient and securefastening for the brace B and reach r. Said brace and reach thus have incommon one attachment at their rear ends, and this is a very -importantfeature of my invention, inasmuch as the reach has to of the forwardaxle being. crowded rearward resist the tendency by the encounter of itstraction wheels with obstructions on the road, and also the tendency ofthe axle being` crowded forward by the strain transmitted to the axlebythe engagement oi' the pinion P with the gear R, and these strains aretransmitted by the reach to the knee f, where they are resisted by vthebrace B, which latter transmits 'the strain to the rigid post K on theforward end of the boiler, and thus completely relieves the rear portionoftheboiler of said strain.' The post K is hollow, and has on one sidean opening, opposite side al rigid horizontal sleeve, Il, projectingtherefrom. Diametricall y through the semi-spherical portion of' thepost K is extendeda counter-shaft, L, one end of which is journaled inthe sleeve h, and the oppositev end projects through the openiug'c, an'dis journaled in a box, c, attached to avertical rib rising from thesleeve s. This countershaft is provided with counter-shaft to foliow theaxle a in its oscillatory movements, while the opposite end of parallelwith the driving-shaft C by means of the sleeve h. Thislineally-confined end of the counter-shaft has attached to it aA pinion,N, which meshes in a pinion, N', mounted cna gudgeon rigidly attached tothe boiler, and on the side of the pinion N' is the gear-wheel O, whichreceives motion from the driving-shaft C, as hereinbefore described.

On the vibratcry7 end is a pinion, P, which meshes in a compensatinggear, R, monntedon the axlea, said compensating gear being adapted tctransmit inotion to the axle at varying speed when turning the axle toguide the engine around curves of the road. l

The engine isguided by means of the usual IL la, which are connected tothe ends of the sleeve s, and' are wound in opposite directions on ashaft, t, which is under the control of the operator, by a hand.-'

wheel on the end,l ofva shaft carrying a worm of the counter-shaft L`IK; and to obviate'such injurious effects I employ check-chains Z,which are at one end `hung loosely on the shaft t,so as to prevent woundon the shaft, and'thus have attachment stationary and indetheir beingtheir rear .pendent of the steering-chains. The opposite ends of thecheck-chainsare securely coupled to the steering-chains at any suitablepoint between the shaft t and the axle -sleeve s. Said check-chainsareof such lengthtthat in the operation of turning the axle laterallythe check-chain which is coupled to the unwinding or payingout steeringchain is drawn taut andcaused to arrest the Inovement cf saidsteering-chain. v
